Paintings aren't copied over

[Ameliorate]

This is semi-intentional, see https://github.com/CivWizardry/DungeonMod/blob/master/src/main/java/pw/amel/dungeonmod/blockcopy/CopyThing.java#L72

This is because paintings don't just work when you copy over their NBT data, so instead you have to do this, and I don't want to figure that out.
